Authorisation of expenditure

(1) The Minister for the time being responsible for finance shall cause to be prepared and laid before the National Assembly, before or not later than 30 days after the commencement of each financial year, estimates of the revenues and expenditure of Botswana for that year. (2) The organisations of expenditure contained in the estimates for a financial year (other than expenditure charged upon the Consolidated Fund by this Constitution or any other law) shall be included in a Bill to be known as an Appropriation Bill which shall be introduced into the Assembly to provide for the issue from the Consolidated Fund of the sums necessary to meet that expenditure and the appropriation of those sums for the purposes specified in the said Bill. (3) If in any financial year it is found— ( a ) that the amount appropriated by the Appropriation Act for the purposes included in any organisation of expenditure is insufficient or that a need has arisen for expenditure for a purpose for which no amount has been appropriated by the Appropriation Act; or ( b ) that any moneys have been expended on any organisation of expenditure in excess of the amount appropriated for the purposes included in that organisation by the Appropriation Act or for a purpose for which no amount has been appropriated by the Appropriation Act, a supplementary estimate showing the sums required or spent shall be laid before the National Assembly and the organisations of expenditure shall be included in a supplementary Appropriation Bill, or in a motion or motions approving such expenditure, which shall be introduced or moved in the Assembly. (4) Where any supplementary expenditure has been approved in a financial year by a resolution of the National Assembly in accordance with the provisions of subsection (3) of this section, a supplementary Appropriation Bill shall be introduced in the National Assembly, not later than the end of the financial year next following, providing for the appropriation of the sums so approved.
